The Gas Spring is a Hydro - Pneumatic Adjusting Element with Pressure Tube, Piston Rod and End Fittings. It Contains High Pressurized Nitrogen.

As Compared to Conventional Coil Springs, Gas Spring has an Extremely Flat, Nearly Linear Characteristic Curve which Facilitates Uniform Comfortable Adjustment or Pivoting Movement. Also, it has Another Advantage Over Mechanical Springs is Damping. When Gas Spring is Installed Piston Rod Facing Downwards, During Extension it First Travels through Gas Portion and then through the Oil Portion. The Oil Dampens the Movement and Speed Reduces Considerably.

The High Pressure Nitrogen Acts with Equal Pressure on Surfaces having Different Cross - Sectional Area of Piston. This Produces a Force in Extension Direction. The Force Depends Upon the Charging Pressure.
